An animal fiber that tribal weavers sometimes use for a rug's foundation in place of wool, as in Gabbeh and Quchan rugs, while the pile itself stays wool. Together with mohair, camel hair and cow hair it is among the less common rug materials, seen mostly in tribal work, and it also turns up in some flat-woven kilims.
A flat-woven rug with no pile, traditionally made in Turkey, Iran, Afghanistan, and the Balkans. Colored weft threads are interlaced with the warp without knots, so both sides look alike. The fibers are typically wool, cotton, or goat hair, and natural dyes often give slight shade variations that are normal, not flaws. Its low profile clears doors easily, and it can hang as wall art. In a knotted rug, "kilim" also names the flat-woven band at each end, where extra weft rows secure the ends beside the fringe.
The long, silky, lustrous hair of the Angora goat. In Persian rugs it is one of several animal fibers, listed together with goat hair, camel hair and cow hair, that can serve as a material but are much less common than the usual wool, cotton and silk; this group is seen mostly in tribal rugs.
The skeleton of a hand-knotted rug: the warp and weft threads on which every pile knot is tied. Cotton is the usual material in city and village rugs because it barely stretches or shrinks with humidity, so the rug keeps its shape, and it is rigid enough to knot through easily; that same rigidity can carry over into the design, which reads as less fluid than on a wool foundation. Wool, and sometimes goat hair, is typical of tribal rugs, whose weavers can use one material for both foundation and pile; it gives more character but a less straight shape. Silk, being finer, permits very high knot counts. The fringes at each end are the foundation's exposed warp ends, so they reveal its material.
Rugs woven by mostly nomadic tribes, chiefly in Iran but also across the Middle East, Central Asia, and North Africa; a few names, such as Bakhtiari and Gabbeh, span tribal and village weaving. Tribes move with their flocks from spring to fall and typically settle in winter to weave on compact, portable looms, so rugs are small, often 4 x 6 ft (1.2 x 1.8 m) or 5 x 7 ft (1.5 x 2.1 m), or runners, and rarely oversized. The flocks' wool, dyed with local plants, often forms foundation and pile; goat hair is also used. Designs, mostly geometric, are passed down and woven from memory without a drawing, so, unlike in city rugs, corners often fail to resolve neatly. Qashqai, Baluchi, and Turkoman rugs are named after their tribes.
A rug base in which the warp and weft threads are wool instead of cotton. It is typical of tribal rugs such as Baluchi, Turkoman and Gabbeh (Gabbeh and Quchan sometimes use goat hair instead), turns up in some Qashqai, Shiraz, small Bakhtiari and Iranian Azerbaijan pieces, and is common in older village and tribal rugs, including some Hamadan and very antique Karaja. Experts use it as a clue to age, since rugs made after about the 1930s usually have a cotton foundation, once machine-spun cotton became widely available. Wool's soft, less rigid structure gives the design a fluid, warm character, and the fringes are sometimes braided or in different colors. The drawback is that wool shrinks and stretches with humidity, so these rugs tend to be less straight than cotton-based ones.
